While the world moved a bit closer to a coordinated effort to contain climate change, the Copenhagen summit last December made it all too clear that we will have to overcome deep divisions on how to reduce greenhouse gas emissions (and how to apportion the cost of doing so). This panel evaluates where we now stand and the prospects for moving forward expeditiously. Equally important, it considers a topic on which considerable progress was made at Copenhagen: mitigating the consequences of climate change. Panelists discussed how to cope with risks ranging from rising sea levels to radical changes in weather patterns, and how to manage the effort in countries that lack the resources to do it on their own.
